I forgot to mention that I got my inspiration from Mexel's MUD HUD, which showed the ammo below the crosshair. I used to use that HUD, but it no longer works with 1.2 GPP, so I decided that I might as well create a new one.
@mooseberry: Thanks. Yes, it can be distracting at the start, but for me it was very convenient once I got used to it.
Yeah, the blue graph is the speedometer (enabled in the menu).
I'm going to update Clean HUD in a day or two - I was notified that the speedometer overlaps with the world time, and I also realized that the HUD alignments are not correct for widescreen resolutions (right now it only works correctly with a 4:3 resolution).
